The kickstarter page has a video where you can check out the video of the ShareRoller. It's kinda hard to wrap your head around this product until you see it in action. You'll also see a lot more pictures of it on the shared bikes, the Xootr scooter, and of course a Brompton.

I asked Jeff if the Brompton adapter will cost extra. He said they will be since each one will be 3D printed, and would probably cost about $95 unless there is demand for a lot of them. If there is a lot of demand, he can have them made, which would make them cheaper.
